CUSHION OR HASSOCK.

SPECIFICATION forming part Of Letters Patent N0. 623,548, dated April 25, 1899.

$0 at whom it may concern.-

Beit known that I, NELLIE F. HURDEL, a

citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented and' produced a I make one form of my invention. Fig. 2 is an edge elevation of the same. Fig.3 is a plan view similar to that of Fig. 1 of a modified form of my invention. Fig. 4 is a side elevation of the same. Fig. 5 is a sectional View of the cushion made by the folding up of the sheet shown in Fig. 3. Fig. 6 is a plan view of a sheet of material properly shaped to form a hassock. Fig. 7 is a perspective view of a hassock when completed. Fig. Sis a detail section of one side of the hassock.

Myinvention consists in makinga cushion out of wood-pulp or other suitable moldable or plastic com position and providing the edges of the same with alternate single and double edges, which upon being folded or made up into a cushion or hassock form have such edges brought together, so that the single alternate edges are brought opposite to and inserted in the alternate double edges, whereby the meeting edges of which are hermetically sealed by cement or otherwise.

Myinvention further consists in providing such cushions or hassocks with an air-tube and valve, by means of which air under pressure may be introduced therein, so that a very light and at the same time firm and elastic cushion or hassock is produced.

In Figs. 1 and 2 I take a plurality of sheets 1 of wood-pulp or other suitable flexible material and cement the same firmly together throughout, except at the double projecting edges 2. These edges are left .uncemented and are bent or shaped so as to leave a parallel series of recesses between them sufficient to receive the cemented single edges 3 of the sheets. The double and single edges 2 and 3 are disposed alternately about the outer edge of the sheet, and the sheet itself is adapted to be folded or bent over upon itself upon the line of the dotted lines 4c,when the single edges 3 will be brought opposite to and inserted in the alternate double edges of the sheets, thereby forming an overlapped joint upon both sides, the joints being previously cement-ed. The projecting double edges 2 are cut away at their ends 5 on the line of the dotted lines at and also cut awayat the point 6,so that when overlapped they wi 11 meet and register with the dotted line 7. The edges, are then cemented, forming air-tightjoints throughout. In Figs. 3

. and 4t thegeneral result is the same,except that the material is molded from a single sheet 8,

with alternate single edges 9 and double edges 10, which upon being folded upon the dotted lines 1l by the insertion of the single edges within the double edges form a cushion of sub stantially the same shape as that previously described. The shapes of both these cushions are preferably similar to that illustrated in Fig. 5.

In Fig. l the double'edges 2 extend entirely around opposite alternate flaps 12, the intermediate alternate flaps being provided with single edges. In Fig. 3 the double edges 10 extend only half-way or around one edge only of each of the flaps 13, the alternate edge or other half of the flap being a single edge.

In Figs. 6, 7, and S the construction embodies the same principle as the figures hereinbefore described, except that the rectangular portions 14 are provided in the sheet, which, being turned up in a vertical position, form the side walls of a hassock such as is shown in Fig. 7. If desired, in forming the hassock the walls 14 are formed with a lap.- over or upset portion 15 at top and bottom, properly stitched or cemented, which serves to reinforce and strengthen the edges, thereby preventing the walls 14 and top and bottom from unduly bulging under the pressure of air within.

- In Fig. 6 the joints of the hassock are similarly formed to the cushion shown in Fig. 1, while the hassock shown in Fig. 7 has its joints formed after the manner illustrated by Fig. 3. The vertical corners of the hassock may be formed in an y suitable and well-known way.

16 represents an air pipe and valve by means of which air is introduced and maintained under pressure in the cushion or hassock, whereby it is prevented from collapsing and is capable of resisting the ordinary pressure or weight put upon the same.

Any known and suitable material may beemployed in constructing my invention. \Vhen made of wood-pulp and inflated, an extremely light and at the same time elastic, strong, rigid, and serviceable cushion or hassock is produced.

In the form of my invention shown in Fig. 1, where the body of the device is composed of a plurality of sheets, I may, if desired, have all the joining edges separate and uncemented, similar to the edges 2, and unite the same by overlapping and cementing in the manner previously described.

As a finish for the article I may cover the cushion or hassock with any suitable or ornamental material, glued or cemented directly thereto, or I may provide the cushion or hassack with any suitable or ornamental covering sewed thereon or otherwise secured.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. As ancwarticleof manufacture,acushion or hassock, the walls or sides of which at the joints are provided with alternate meetalternate single and double edges, the outer line of the double edges projecting out beyond the lines of the single edges.

5. As a new article of manufacture, a cushion or hassock, having inclosing sides, top and bottom,the bends 01' angles of which overlap or are upset upon the material, the joints of which are formed of alternate single and double edges united substantially as described.

6. As a new article of manufacture, an inflatable cushion or l1assock,tliejoints of which are formed of alternate single and double edges united substantially as described.
